CO2 capture is currently performed by using inefficient technologies that entail a high energy consumption.

In the context of the CARMOF Project (funded by the European Commission’s H2020 program) European partners design innovative CO2 absorbing materials at nanoscale (carbon nanotubes, CNTs, metal organic frameworks, MOFs) using highly adaptable 3D printers for scaled-up manufacture to realize membranes.

The challenge of the project is multiple:

  • Design a monolith of CO2 absorption from carbon and organometallic nanotubes
  • Develop an industrial 3D printing process for the manufacture of monoliths
  • Build demonstration pilots in industrial environments (petrochemical industry and cement works) capable of capturing CO2

The project focuses on the (hybrid) solid sorbent development for CO2 capture. Preliminary formulations of 3D printing composite pastes had promising results on the CO2 adsorption capacity. It’s believed that MWCNT’s presence enables gas transport to the active CO2 adsorption sites. Other materials combinations are being further explored and 3D printed.

From the point of view of materials development, the innovations expected are related to an increase of their adsorption area, while CO2 recovery will be carried out by means of new advanced and highly efficient heating technologies as those made possible due to the application of the Joule effect.

The project’s aim is to have a higher technology level to use the results at industrial facilities. These innovative structures will be installed at the emission points of ceramic, petrochemical and Steel industries.
